Horst Geyer claims Mosquito

Hello. Does anyone have any information on the following. It is an English translation of a report by Horst Geyer on his claim of a photo reconnaissance Mosquito on 6th November 1943 in a Me-109G adapted for high altitude flying. He took off from Achmer.
Below is an unedited extract. [Square brackets are mine].


So I was in haste to come in an acceptable shooting position at about 200m distance I released my gun-fire but there was only one shoot, my gun was frozen and I had to reheat the system. With a second attempt I had visible success, different parts of the Mosquito nearly touched me and a strong smoke from the right wing obviously the engine stayed behind the aircraft. After some seconds the Mosquito disappeared in the big clouds. It was impossible for me to follow because some ice has been developed at my wingtips.
My copilot [wingman - Uffz. Herzog] who did not understand or follow my warning continuing the flight into the clouds and missed since then.
Navy-observer at the beach of Helgoland have reported 2 aircraft (1 two-engine, 1 single-engine) plunged direct out of clouds into the sea.
This reconnaissance ‘Mosquito’ was the first shooten-down by fighter-aircraft over Germany. It was my 27. victory. For this I was awarded with ‘Deutsches Kreuz [German Cross] in Gold’ by Reichsmarschall Göring who was to visit (and inspect) the Erpr.Kdp 25 on Nov.17.1943.
He was accompanied by General Adolf Galland and members of his staff.

I cannot find any ref to this Mosquito. Any help identifying it would be appreciated.
Thanks.
